Like title says, would like to pick up a 26, 28 or 30" barrel for a 870 remington 12 ga that will take at least 2&3/4 and 3" shells. Vent ribbed w/ screw in style choke would be ideal. If you have extra chokes thats a plus.If it has fiber optics even better! Looking to use to convert my slug gun over for bird hunting.
